Arrival time in Calais (returning to London)

Hey, can anyone tell me roughly what time the Highlights tour gets back to Calais, for the trip back to London?<BR><BR>If not, will my contiki paperwork (when i get it!) say what time we arrive? I need to book a train ticket from calais to Paris, and depending on the time we get in to Calais, i might also need to book a night's accommodation...<BR><BR>Thanks <img src="http://connect.contiki.com/groupee_common/emoticons/icon_smile.gif" alt="Smiler" width="15" height="15"><!--graemlin::)-->
